The new iMacs boast LED-backlit 21.5- and 27-inch widescreen displays in an edge-to-edge glass design and all aluminum enclosure. They’re available with Intel (INTC) Core 2 Duo processors starting at 3.06 GHz, and Core i5 and i7 quad-core processors for even better performance. The low-end model is priced at $1,199, the same as the past generation, but its high-end sibling is now $200 cheaper, at $1,999.

The new MacBook features an 13.3-inch LED backlit display, a multitouch trackpad, and a $999 price tag. Though still housed in white polycarbonate plastic, it features an updated unibody design borrowed from the MacBook Pro.

The successor to the Mighty Mouse, Magic Mouse, eliminates mechanical buttons, instead, employing the same multitouch surface found on the iPhone, iPod touch, and Mac notebook trackpads, allowing users to navigate their desktops with simple gesture commands.

Accompanying the Magic Mouse is a a new Apple Remote. It’s got a new design and is, predictably, housed in aluminum.

Finally, Apple (AAPL) also updated the Mac mini. While its design is largely identical to that of its predecessor, it offers far more storage. Starting at $599, the entry-level Mac mini features a faster 2.26 GHz Intel Core 2 Duo processor and 2GB of DDR3 1066 MHz memory, a 160GB hard drive, five USB 2.0 ports, FireWire 800, Nvidia GeForce 9400M integrated graphics and a SuperDrive.

There’s also a new $999 Mac mini that’s specially configured with a Mac OS X Snow Leopard Server. It’s outfitted with two 500GB hard drives for a total of 1TB of server storage.

Quite a refresh and one analysts are already crowing about. In a bulletin released after the announcement, Piper Jaffray’s Gene Munster said Apple’s new machines will undoubtedly improve the company’s prospects for the December quarter.

“We expect the new iMacs, and to a lesser degree the new Mac minis, to help the desktop category rebound in the Dec. quarter,” Munster wrote. “In other words, the headwind that existed in the Sept. quarter due to aging Mac desktops has now turned into a tailwind for Mac units in the Dec. quarter….Bottom Line: Street Mac numbers may also be conservative if positive trends continue coupled with new Macs in the quarter.”

Also: A new LED display, 24-inch built-in iSight, built-in speakers and MagSafe.

Cost: $899; available in November.

As for the existing standard white plastic MacBook model, Apple (AAPL) is dropping the price to $999, according to Steve Jobs.

Back to the refreshed line, MacBook users have been asking for “a metal enclosure, faster graphics, and LED display,” Jobs explains. “We’re giving it to them.”

Similar features as the new Pro: unibody enclosure, glass trackpad, faster graphics Nvidia 9400 graphics chip and a five-time increase in graphics performance. The new display is designed with laptops in mind.

And continuing a theme at this event, the new MacBook is environmentally friendly. It has also been awarded the EPA EPEAT designation.

The new metal 13.3-inch MacBook sells for $1,299. The $1,599 model buys a faster processor.

Units start shipping today, and will be in stores tomorrow.

One of the investments we make is to introduce new products that initially cost more because they deliver an entirely new level of value to the customer. Then we ride the cost curves down with value engineering and volume manufacturing, leaving us far head of our competitors. We have some of these types of investments in front of us that I can’t discuss.”

– Apple Chief Operating Officer Tim Cook, July 21, 2008

The media will gather tomorrow at Apple’s Cupertino, Calif., headquarters for an invitation-only event–presumably about updates to its MacBook and MacBook Pro lines. And as with every Apple (AAPL) product launch, tomorrow’s has been preceded by feverish speculation about what form, exactly, those updates will take. Among the rumors currently making the rounds:

• Apple will uncrate a new line of MacBooks whose cases are carved from a single brick of aircraft-grade aluminum.
• Apple’s refreshed MacBook line will include a machine priced at below $1000, perhaps even as low as $800.
• The new MacBooks will feature glass, multi-touch trackpads and LED-backlit displays.
• They’ll swap out Intel’s chipset–not the central processor–for Nvidia’s MCP7A, which reportedly blows the doors off Intel’s G45 in the graphics department.
• Blu-ray will be offered as an option on high-end models.
• Finally, Apple’s new line of portables will include the unmatchable “state-of-the-art new product” to which Apple CFO Peter Oppenheimer and COO Tim Cook referred earlier this year, and that product will be a tablet. Something along the lines of the “MacBook Touch” described by MacDailyNews back in July.
  

  Think MacBook screen, possibly a bit smaller, in glass with iPhone-like but fuller-featured multi-touch. Gesture library. Full Mac OS X. This is why they bought P.A. Semi. Possibly with Immersion’s haptic tech. Slot-loading SuperDrive. Accelerometer. GPS. … App Store-compatible, able to run Mac apps, too.”

An interesting spread of rumors, some quite likely, others improbable … and yet entirely plausible because, after all, it’s Apple we’re talking about. We’ll find out which of these proves true tomorrow at 10 a.m. PDT. I’ll be covering the event live, so be sure pay us a visit tomorrow.

This morning Apple (AAPL) refreshed both its MacBook and MacBook Pro lines, adding Intel’s Penryn Core 2 Duo chipset (up to 2.4 GHz for the MacBook and up to 2.6 GHz for the MacBook Pro). As Apple’s flagship portable, the MacBook Pro now boasts the same multitouch trackpad found in the MacBook Air and an LED backlighting option for the 17-inch model. All but the low-end MacBook feature a two-gigabyte RAM, with a build-to-order option that allows for their upgrade to a four-gigabyte RAM. New Macbooks are priced from $1,099 to $1,499, new MacBook Pros from $1,999 to $2,799.

CrunchGear has published a photo (or perhaps Photoshop) of the subnotebook that Apple is reportedly planning to launch at Macworld ‘08. The machine–if it is indeed real–is thin as all get-out, but apparently quite well-endowed in the trackpad department.
